In EGPRS mobile electron communication equipment, receive and manage the method that downlink radio link is controlled data block
The application be submit on April 28th, 2008, the dividing an application of application number is 200680040392.8, denomination of invention is " receive in EGPRS mobile electron communication equipment and management downlink radio link is controlled the method for data block " patent application.
Technical field
The present invention relates to a kind of mobile communication system, more specifically, relate to a kind of for receiving at enhancement type general use grouping wireless electric system (EGPRS) mobile electron communication equipment and management downlink radio link is controlled the method for (RLC) data block.
Background technology
Global system for mobile communications (GSM) is the main global standards for 3G wireless speech and data communication.In typical gsm communication system, in source, encode to voice and/or data in place, and be transmitted through the network to receiver.When receiving transmitted data, receiver is carried out channel equalization and decoding, so that voice and/or data are returned and can be identified form, thereby passes to user.GSM/EDGE (enhanced data rates for GSM evolution) represents the latest stage of GSM standard evolution.EDGE is used modulation scheme in existing GSM frequency spectrum, to realize the gross data speed up to 384kbit/s.
General packet radio (GPRS) is developed to the packet data network for GSM standard.GSM cell phone is used GMSK (Guassian Minimum Shift Keying) (GMSK), for the modulation in physical layer.GSM standard has experienced some revisions, and each revision all makes network be promoted.The once revision of this standard is Enhanced General Packet Radio Service or EGPRS, it is by use 8PSK modulation and GMSK that higher data rate is provided in physical layer, and by using adaptive coding and incremental redundancy that the improvement in performance of radio link control (RLC) and media interviews control (MAC) sublayer is provided.These changes of physical layer are very important for the EDGE assembly of modern GSM/EDGE network.
In EGPRS, the rlc/mac layer of network either side is positioned in mobile electron communication equipment or travelling carriage (MS) and base station sub-system (BSS).Equity RLC/MAC entity is used one or more RLC/MAC protocol Data Unit (PDU) to communicate.Each PDU is used piece sequence number (BSN) to be numbered.In answer-mode, by sending and receiving RLC/MAC entity, with permission, by sending piece additional and that increment information correction makes mistakes, follow the tracks of BSN, to help decoding.For down link (BSS to MS) state, the state of the piece that BSS poll MS is received with request, and MS replys with status report (packet downlink ACK/NACK) in section where necessary.For up link (MS to BSS) state, BSS regularly sends to status report (packet uplink ACK/NACK) each communication MS.
At third generation partner plan, technical specification group digital cellular communication system (stage 2+), GPRS (GPRS), travelling carriage (MS)--base station system (BSS) interface; (RLC/MAC) agreement 3GPP TS 04.60V8.27.0 is controlled in radio link control/media interviews, has proposed the process of using at the radio interface place that controls (MAC/RLC) layer for GPRS media interviews control/radio link in 2005 9 months.
RLC function has defined for being the process of RLC/MAC piece and link circuit self-adapting by logic link control (LLC) PDU Segmentation and Reassembly.Defined different RLC/MAC block structures, for data transmission and control message transmission.RLC/MAC block structure for data transmission is different for GPRS and EGPRS, and identical RLC/MAC block structure is for control message transmission.EGPRS down link RLC data block comprises one or more expansion (E) bit that is used to indicate the optional expansion of appearance eight bit groups (octet) in RLC data block.Although think that E bit is header fields, it transmits in the data division of piece.When E bit is reset to 0, optional expansion eight bit groups are followed thereafter immediately, wherein this expands the length indicator (Ll) that eight bit groups comprise 7 bits of the length (i.e. the number of eight bit groups) that is used to indicate LLC PDU, and is used to indicate the E bit that any other expands eight bit groups.If E bit is made as to 1, does not follow expansion eight bit groups, but follow immediately LLC PDU.Therefore,, when the E bit of data block is set as to 1, this indication LLC frame finishes in current RLC data block.Then, the RLC/MAC assembly in travelling carriage (MS) is passed to upper strata by data, carries out the fluffing check (error check) of self on upper strata.
In the downlink transmission of EDGE data block, travelling carriage (MS) is decoded to data block sometimes mistakenly, but CRC check will be passed through.For example, if E bit is reset to 0 mistakenly as the result of packet corruption, RLC data block will be misunderstood the length indicator (Ll) that is translated into remaining LLC Frame in this RLC data block.This causes LLC Frame to finish too early.Finally, this mistake in LLC layer, detected, abandon whole IP grouping and (BS) asks this grouping again to base station, cause time delay and data throughout reduction.
Summary of the invention
In aspect of this specification, the E bit of realizing resetting mistakenly before process data block detects.As mentioned above, EGPRS agreement regulation: if E bit has been reset to 0, the subsequent byte of RLC data block means the length indicator (Ll) of the length (numbers of eight bit groups) of the LLCPDU finishing in this RLC data block.Therefore,, if length sum is greater than the number of byte in data block, this RLC data block is counted as destroyedly, and before passing to LLC layer, abandons this data block, thereby has overcome the time delay of above-mentioned discussion and the shortcoming that data throughout reduces.
Substantially, a kind of method has been proposed here, comprise: a) receive the data block with at least one bit and at least one value, wherein said at least one bit is for representing the appearance of associated growth data the length of growth data described in described at least one value representation; B) determine the logical value of described at least one bit; If described bit is the first logical value, c1) calculate described in each and be worth sum; C2) determine the size of described growth data; And c3) if described and surpass described size, abandon described data block and perform step a); Or, if described bit is different from described the first logical value, c4) and execution step is a).
More specifically, here proposed a kind of method of controlling (RLC) data block for managing the downlink radio link of enhancement type general use grouping wireless electric system (EGPRS) mobile electron communication equipment, having comprised: a) receive described down link RLC data block; B) determine whether expansion (E) bit in the header of described RLC data block has been reset to zero, thereby represent to have expansion eight bit groups in described RLC data block, described in each, expand eight bit groups and comprise and be used to indicate the length indicator (Ll) of expanding the number of eight bit groups in eight bit groups described in each; C) if described expansion (E) bit is not reset to zero, return a), otherwise d) calculate and expand each length indicator (Ll) sum of eight bit groups from each; E) calculate the number of byte in described RLC data block; And f) if described and surpass described byte number, abandon described RLC data block, otherwise return a).
